Abstract:
A coulometric cell employs a nonconductive inorganic envelope containing an electrolyte and an expansion bubble. First and second spaced electrode members extend from outside of said envelope, through the wall thereof and into said electrolyte. Each electrode member comprises a nonconductive inorganic substrate having at least the same coefficient of thermal expansion as that of the inorganic envelope. Each substrate carries a thin conductive film which extends from within to outside of said envelope. The envelope is bonded in fluidtight arrangement about the periphery of the electrode members where they pass through the wall thereof.
Abstract:
An electrochemical timer has a metal cathode electrode in the form of a container housing an electrolyte, an anode electrode and an elongated nonconducting anode support means having extremities larger than the region between the extremities. The intermediate region of the support means carries the anode of the device and the extremities of the support means serve to space the anode from the cathode.
